Clothing terminology ranges from the arcane (watchet, a pale blue color name from the 16th century) to the everyday (t-shirt), and changes over time in response to fashion which in turn reflects social, artistic, and political trends.

Despite the constant introduction of new terms by fashion designers, clothing manufacturers, and marketers, the names for several basic garment classes in English are very stable over time. Gown, shirt/skirt, frock, and coat are all attested back to the early medieval period.

Gown (from MedievalLatingunna) was a basic clothing term for hundreds of years, referring to a garment that hangs from the shoulders. In Medieval and Renaissance England gown referred to a loose outer garment worn by both men and women, sometimes short, more often ankle length, with sleeves. By the 18th century gown had become a standard category term for a women's dress, a meaning it retained until the mid-20th century. Only in the last few decades has gown lost this general meaning in favor of dress. Today the term gown is rare except in specialized cases: academic dress or cap and gown, evening gown, nightgown, hospital gown, and so on (seeGown).

Shirt and skirt are originally the same word, the former being the southern and the latter the northern pronunciation in early Middle English.

Coat remains a term for an overgarment, its essential meaning for the last thousand years (seeCoat).

Names for new styles or fashions in clothing are frequently the deliberate inventions of fashion designers or clothing manufacturers; these include Chanel's Little Black Dress (a term which has survived) and Lanvin's robe de style (which has not). Other terms are of more obscure origin.

Clothing styles are frequently named after people—often with a military connection:

The Jinnah Cap is a fur qaraqul hat named after the founder of Pakistan, Muhammad Ali Jinnah.

The Garibaldi jacket or Garibaldi shirt were bright red woolen garments for women with black embroidery or braid and military details popular in the 1860s; they are named after the Italian revolutionary Giuseppe Garibaldi who visited England in 1863.

The Eisenhower jacket or "Ike" jacket is a waist-length, military jacket of World War II origins. Called the "Jacket, Field, Wool, M-1944", it was commissioned by then General Dwight Eisenhower as a new field jacket for the US Forces in Northern Europe. The jacket was based on the British Army 'Battle Dress' jacket of the same era.

The Mao jacket is a very plain (often grey), high-collared, shirtlike jacket customarily worn by Mao Zedong and the people of China during his regime. Its drab design and uniformity was a reaction to pre-Revolution class distinctions of clothes, with elites dressing in elaborate silks, while poor laborers wore very rough clothes.

The Nehru jacket is a uniform jacket without lapels or collars, popularized by Jawaharlal Nehru, the first Prime Minister of independent India.

Costume historians, with a "rearward-looking" view, require names for clothing styles that were not used (or needed) when the styles were actually worn. For example, the Van Dyke collar is so-called from its appearances in 17th century portraits by Anthony van Dyck, and the Watteau pleats of the robe á la française are called after their appearance in the portraits of Antoine Watteau.

Similarly, terms may be applied ahistorically to entire categories of garments, so that corset is applied to garments that were called stays or a pair of bodies until the introduction of the word corset in the late 18th century. And dress is now applied to any women's garment consisting of a bodice and skirt, although for most of its history dress simply meant clothing, or a complete outfit of clothing with its appropriate accessories.
